corporation of Delaware Filed Apr. liti, 1961, Ser. No. 11%,?26 6 Claims. (Ci. 19d-2) Our invention relates to an escrow bucket and coin guide and more particularly to an :improved escrow bucket and coin guide construction for use with a merchandising machine which is adapted to give change.

As the number of different kinds and brands of merchandise dispensed by a merchandising machine in response to the deposit of various sums representing respective price increases, it becomes important that the merchandising machine be adapted to give change. There are Vknown in the prior art coin mechanisms which are adapted to give change `when a sum in coins in excess of .the purchase price of a selected article is deposited in the machine. Not only should the mechanism give change, but also it is desirable that coins of the denomination given in change which are deposited in the machine in order to make a purchase be `added to the supply of coins available to be given in change.

In some change making mechanisms of the prior art, coins of the denomination given in change which are deposited in the machine are retained on edge on a guide member leading to the change coin tube. Coins of other denominations deposited in the machine are held in escrow by a suitable means such, Afor example, as an escrow bucket. When a purchase has been made, coins of the denominations given in change are permitted to move into the change coin tube and the escrow bucket is actuated to permit the coins to fall into the coin box. If for any reason the customer desires the return of deposited coins before a selection is made, he can actuate a coin return mechanism which causes al1 coins which have been deposited in the machine to be returned.

While the mechanisms of the prior art described above function satisfactorily for the most part, they embody a number of defects. The coin guide which receives coins of the denomination given in change and which directs them to the coin change tube when a purchase is made must be suiiiciently wide to permit the passage therealong of a newly minted coin. We have discovered that, owing to this fact, two thin coins supported to edge on .this quide may overlap and cause jamming of the coin mecha msm.

The coin mechanisms of the prior art described above employ an escrow bucket of the clam-shell type in which the two sides of vthe bucket are pivoted at the top thereof. When a purchase is made, one of the two walls is moved away from the other to permit the coins to fall to the coin box. When the coins are to be returned, the other wa'll of the bucket is moved to permit the coins to fall to a chute which directs them to a return slot. The dificulty which has been encountered with a mechanism of this type is that in operation of the bucket when an actuated wall returns to its initial position a coin may be trapped between the lower edges of the two walls so that a coin either is not accepted or is not returned to the customer, both of which results clearly are undesirable.

We have invented an improved escrow bucket and coin guide construction which overcomes the defects of mechanisrns of the prior art described above. Our improved escrow bucket and coin guide holds only a single coin of the kind given in change on edge on a guide for movement into the change coin tube when the coins are accepted. It thus obviates the possibility that two thin coins of the kind given in change will overlap and jam the mechanism. We so arrange our escrow bucket that the possibility of a coin being trapped lbetween the sides of the bucket as they return to their normal relative position is obviated. We provide means for moving one of the shelf walls and the movable section of the coin guide supporting the single coin of the kind given in change as a unit to return deposited coins to the customer. When the coins are to be accepted, the other wall of the guide moves to permit the coins to fall to the coin box.

`One object of our invention is to provide an improved escrow bucket and coin guide which overcomes the defects of coin handling assemblies of the prior art.

Another object of our invention is to provide an escrow bucket and coin guide which obviates the possibility that two deposited coins intended to replenish the supply of change will overlap to jam the mechanism.

A further object of our invention is to provide an escrow bucket and coin guide in which there is no danger of a coin being trapped between the edges of the escrow bucket walls.

A further object of our invention is to provide an escrow bucket and coin guide in which a movable section of the coin guide which directs a coin to the change tube and a wall of the coin bucket moves as a unit to return coins to a customer.

Other and further objects of our invention will appear from the following description.

In general our invention contemplates the provision of an improved escrow bucket and coin guide in which one of a pair of co-operating escrow bucket walls is pivoted adjacent its top and the other of the walls is pivoted adjacent its bottom. We form one of the walls as an integral part with a movable section of the coin guide leading to the change tube. When a purchase is made, one of the walls is moved to permit deposited coins to drop into the coin box and the coin supported on the movable section of the coin guide is permitted to move into the change tube. When the coin return mechanism is operated, the escrow bucket wail carrying the movable guide section is moved to cause all the coins to be returned to the customer.

In the accompanying drawings which form part of the instant speciiication and which are to be read in conjunction therewith and in which like reference numerals are used to indicate like parts in the various views:

FIGURE 1 is a side elevation of our escrow bucket and coin guide and its associated structure.

FIGURE 2 is a sectional view of our escrow bucket and coin guide taken along the line 2-2 of FIGURE 1 and drawn on an enlarged scale.

FIGURE 3 is a perspective view of the operating parts of our escrow bucket and coin guide removed from their mountings to illustrate their operation of the parts to accept coins when a purchase is made.

FIGURE 4 is a perspective View of the operating parts of our escrow bucket and coin guide removed from their mountings to illustrate the operation of the parts when deposited coins are returned to the customer.

Referring now to FIGURE l of the drawings, our escrow bucket and coin guide forms part of a coin mechanism, indicated generally by the reference character 1li, having a main supporting plate 12 formed with side flanges 14 and 16 having lateral extensions 18 and 2l?. In a manner known to the art, the support plate 12 carries a coin separator and slug rejector, indicated generally by the reference character 22, which separates coins deposited in a coin slot 24 according to the denomination while rejecting slugs. After having been separated, coins from the slug rejectors 22 pass through a totalizer mechanism, indicated generally by the reference character 26, which in a manner known to the art establishes a credit corresponding to the sum deposited and releases operating mechanisms corresponding to articles at least the purchase price of which has been deposited.

Coins leaving the totalizer mechanism 26 enter our coin guide and escrow bucket mechanism, indicated generally by the reference character 28, Let us assume by way of example that the coin mechanism with which our escrow bucket and coin guide is to be used is adapted to handle quarters, dimes, and nickels. Assume further that the mechanism is to give change in nickels as required. Nickels leave the totalizer mechanism 26 along the path indicated by the broken line arrows in FIGURE l while dimes and quarters leave the mechanism 26 along a path indicated by the dot-dash arrows in FIGURE l. The first nickel leaving the totalizer 26 is guided to a position at which it rests on a movable coin shelf or guide portion 30 which is normally retained in the position shown in FIGURE l by a means which will be described hereinafter. In the course of its movement, this rst nickel passes by a feeler 32 disposed in the path of the nickel passing to the movable shelf 30. We mount the feeler 32 on a shaft 34 supported between a central wall 36 of the coin guide mechanism 28 and an outer guide wall 3S secured to the Wall 36 in spaced relationship thereto by means of screws or the like 4i). We mount a counterweight 42 on shaft 34 for movement therewith normally to cause the nger 32 to occupy the position shown in FIGURE 1. To ensure that a nickel entering the mechanism 23 strikes the linger 32 at a point closely adjacent to the shelf 34, we mount a coin guide member 44 on the wall 36. A coin entering the mechanism 28 is guided by the portion 44 along a path such that it strikes linger 32.

As the rst nickel entering the mechanism 28 pivots the linger 32 in a clockwise direction as viewed in FIG- URE l, it moves to a position at which it rests on the movable section 3i?. This nickel is retained on the movable shelf section by means of a stop 46 carried by an arm 43 supported on a hinge 50 on the back of the support plate 12 and normally urged by a spring to a position at which the stop 46 extends through an opening 54 in plate 36 to intercept a coin such as a nickel rolling down the movable chute portion 30.

When a purchase is made in a manner to be described hereinafter, stop 46 is moved out of the path of the nickel on section 3G and the nickel rolls along a stationary shelf section 5S carried by the plate 36 until it falls into a change coin tube Se carried by the frame 1li. We provide our mechanism with a feeler arm 58 pivotally supported on a pin 6d carried by the outer wall 38. A feeler 62 on the end of arm SS is adapted to sense the presence of a full supply of change coins in the tube 56. When the tube 56 is full, a nickel rolling down the shelf portion 54 toward the tube engages feeler 62 to pivot arm S8 in a clockwise direction as viewed in FIGURE l. A link 64 pivotally supported on a pin 66 on the arm S8 normally rests on a lug 68 on the arm S'. Movement of the link 64 in a counterclockwise direction is limited by the interengagement of a lug il? on the arm 58 and an otiset 72 on the link 64. When, in response to the presence of a full supply of change coins in the tube Se, arm S3 rotates in a clockwise direction as viewed in FIGURE l, link 6 4 moves in a clockwise direction to a position at which a stop 76 on the end of the link is in a position at which it blocks an onset lug '7S carried by an arm S0 supported by shaft 34 for rotation therewith. Thus when a full supply of change coins is contained in tube 56, shaft 34 cannot rotate owing to the position of vstop 76 and a coin 'such as a nickel entering the mechanism 2S and striking finger 32 cannot rotate the linger but is directed to the right as viewed in` FIGURE 1 to passrbelow guide portion 44 and into the escrow bucket indicated generally by the 'reference character 82.

Referring now to FIGURES l and 2 the escrow bucket S2 includes a iirst wall 34 rotatably supported on respective stub shafts 86 and 33 carried by a plate 9) secured to a rib or divider 92 by means of a screw 94 and carried by the wall 36. It will be seen that the movable shelf portion 30 is formed integrally with the wall 84.

We pivotally mount the other wall 96 of vthe escrow bucket 82 on a pair of pivots $3 and 1511. Shaft 9S ris carried -by a plate 162 secured to la boss 164- on the support plate 36 by a screw or the like 166. Shaft 10) is disposed in 4a bearing 163 formed -in the wall 36.

From Ithe structure thus far described, it will be apparent that the wall 84 of our escrow bucket is mounted for pivotal movement adjacent its lower end while the wall 96 is mounted for pivotal movement adjacent ifts upper end. We form the lower end of the wall 96 with bifurcations or ngers 11i) adapted to move into openings 112 formed in the lower end of wall 84 between shafts E6 and 38. In a manner to be described hereinafter, walls 84 and @e normally are urged to relative positions at which ingers bear lagainst the upper ends of 'the openings 112 as viewed in FIGURES l and 2.

Referring .to FIGURE l, a housing 114 carried by the frame 1li slidably supports a coi-n return rod 116 adapted to be actuated by a knob 113. We pivotally mount a coin return bellcrank 12? on a shaft 122 carried by plate 12. One end 124 of bellcrank 120 is disposed between a pair of pins 126 and 12S carried by rod 116. We form Athe end 131BJ of bellcrlank 12) with a slot 132 adapted to receive a pin 134 carried by the coin return link 136i.

Refer-ring now to FIGURES l and 4, a spring 13S` connected between a pin 140 on the link 136 and la pini 142 on 4a second link 144 provides a resilient driving' connection between the links 136 and 144i. When a customer wishes the return of deposited coins before he had made a purchase, he pulls the knob 113 Ito the left as viewed in FIGURES l and 4 -to pivo-t bellcrank 120 in la clockwise direction to Iurge link 136 downwardly and to move the link 144 downwardly through the medium of spring 136. When the link 144 moves downwardly, a roller ior pin 146 carried by the link and extending lthrough a wall 12 engages the lower end of a slot 148 formed in a @slide 15d supported for vertical movement on a pair of pins 152 and 154 carried by the wall 36. A spring 156 supported by a pin 158 on the wall 36 bears between a boss 160 carrying pin 152 and a lug 162 formed on the slide 150 normally to urge the slide to a position at which the lower ends of a pair of slots 163 and 165 engage pins 152 and 154. A slot 164 formed in an otfset end 166 on the slide 15th receives a pin 168 carried by a crank arm` 17@ rotatably supported on a shaft 172 carried by wall 36. From the structure just described, it will be apparent that when slide moves downwardly under the action of bar 144, crank pivots in a counterclockwise direction as viewed in FIGURE 4. The bifurcated end 174 of crank 170 receives a pin 175 carried by a crank 178 securedto shaft 88 for rotation therewith. Thus whenA crank 170 rotates in a counterclockwise direction in the marmer described, shaft S8 is driven to move wall S4 and the movable coin shelf portion Sil to the broken line position shown in FIGURE 4 lto permit a nickel on the movable shelf portion and the coins in the bucket S2 to fall downwardly and out through en opening 18o formed by boss 92 and by a guide S2 to a chute 184 which guides the coins to a suitable coin return opening (not shown) at which they are received by a customer.

Referring now to FIGURES 1 to 3, the operating mechanism of a machine with which our escrow bucket and coin guide is used may include a pull rod 136 slideably supported in `a suitable housing (not shown) and having a linger ISS adapted `to drive an operating bar 19t) in a manner known to `the `ar-t when the pull `rocl Ibo is moved to the left :as viewed in FIGURE 3. When this occurs, the operating bar pulls la link i192 to the left as viewed -in FIGURE 3. A slot in the link 1&2 receives a pin 1% carried by an arm 193 of a -bellcrank 29o p-ivotally supported on a shaft 292 carried by ythe plate 12. A guide pin 224 carried by the pla-te 12 rides in a slot 296 in a bellcrank 26) to guide fthe crank in its movement. A pin connects an arm 2l@ of bellcrank 2th) to one end of `a driving link 212 having a curved slot 2id which receives a pin 21rd carried by the panel l2 to guide the link in its movement. The lbiftlrcated end 21S of link 222 receives a pin 229 carried by `a locking bar 222 adapted to be freed for movement upon the deposit in the machine of a sum in coins aggregating the purchase price of a selected article in a manner known to the art.

A pin 228 pivotally connects the locking bar 222 to an arm 22d rotatably supported on a shaft 226 carried by panel l2. ken the bar 222 is freed and las rod 186 is moved to 'the left as viewed in FIGURE 3, it drives bar 19o and link 192 to rotate bellcrank 29d in a counterclockwise direction yto move link 212 upwardly. Owing to the .interaction of slot 2M- a-nd pin 2te, the upper end 218 of link 222 moves locking bar 222 Ito the left to rotate arm 224 in a counterclockwise direction. Arm 224 carries a pin 236 adapted 'to engage a bifurcation 232 on an escrow bucket operating arm 234 rotatably supported on a shaft 236 carried by the panel l2 and the wall 36. A spring 235 surrounding the shaft 236 beans between a pin 24u carried by a wall 3o and a pin 242 on the arm 234 normally to posit-ion the arm as shown in FIGURE 1. When arm 234 is moved -in a counterclockwise direction under the action of lar-m 224,

a co-unterclockwise direction on a shaft 25o' carried by i wall 3o. A pin 252 pivotally connects member Zei-8 with a link 254 connected to a crank 2:36 on shaft llo@ by la spring 25.3 extending between a pin 2o@ riding in a slot 262 in link 254- aid a pin 263 carried by the link.

When member 242 rotates in a counterclockwise direction, it pulls link 25d downwardly as viewed in FIP- URE 2 to rotate crank 25o in a counterclockwise direction to move wall 96 away from wall 84- to permit coins in the bucket S2 to drop through an opening 264 formed on the side of boss 92 remote from opening 18@ to a suitable coin box 265 disposed below the bucket. In the course of its movement downwardly, link 254 causes an offset portion 26S of the link to carry arm i8 away from the wall 36 to move the projection or lug 46 out of the path of a nickel on shaft portion 31B to permit the nickel to roll into the coin tube.

In operation of our coin bucket and escrow shelf, when a purchase is made on a machine provided with our assembly, coins deposited in the slot 24- pass through the coin separator and slug rejector 22 to the totalizer 26. The totalizer 2o operates in a manner known to the art to establish a credit corresponding to a sum in coins deposited in the machine. In the course of this operation, when a sum equalling at least the purchase price of an article has been deposited, bar 222 is free to permit a purchase to be made and at the same time the change giving mechanism is conditioned to give a sum in change equal to the difference between the purchase price of a desired article and the sum in coins deposited in the machine.

Coins of a denomination which is given in change, such for example as nickels, pass out of the totalizer 26 along the path indicated by broken lines in FIGURE 1. The irst of these coins coming from totalizer 26 pivots feelery 32 in a clockwise direction as viewed in FIGURE 1 and comes to rest on the movable shelf portion 3l) in which it is held by the lug 46. Nickels 'following the rst nickel Corning from the totalizer 26 cannot pivot the feeler 32 owing to the presence of the nickel on the movable shelf protion 34B and are directed by the feeler to the bucket 82. Dimes and quarters leaving the totalizer 26 along the path indicated by the dot-dash lines in FIGURE 1 fall into the bucket 82.

When a purchase is made, bar 186 is moved to the left as viewed in FIGURE 3 to pull link 192 to the left to rotate bellcrank 2th@ in a counterclockwise d1'- rection to drive link 212 upwardly to cause its upper end to move bar 222 to the left. This movement of bar 222 rotates arm 224 in a counterclockwise direction to cause pin 23? to drive arm 234 in a counterclockwise direction. Upon this movement of arm 234, pin 244 engages the cam surface 24o to move member 248 in a counterclockwise direction. When this occurs, link 254 is pulled downwardly to rotate crank 25o in a counterclockwise direction to move wall 96 away from wall 84. When the bucket b2 opens in this manner, coins in the bucket fall down through opening 264 to the coin box 266. In the course of the movement downwardly of the link 25e, the portion 26S of the link actuates arm 48 against the action of the spring carried by the hinge 50 to move stop do out of the path of the nickel on the movable shelf portion 39. This ycoin then rolls down track 55 to the coin tube 56.

If a full supply is in the change coin tube 56, then the top coin in the tube actuates feeler 62 to move arm 53 to a position at which the stop '76 on the link 64 is in the path of movement of the lug 78 on the arm 30. In this position of the parts none of the nickels coming from the totalizer 26 are permitted to move onto shelf portion 30 but are all directed into the bucket 82.

If after a sum in coins has been deposited in the slot 24 so that the rst nickel has come to rest on the movable shelf portion E@ and the other coins have fallen into the bucket 82 and the purchaser wishes the coins returned, he pulls bar llllo to the left as viewed in FIGURES 1 and 4. Upon this operation of the bar, the coin return bellcrank is driven in a clockwise direction as viewed in FIG- URES 1 and 4 to move links 136 and 144 downwardly. This movement of the links causes link to be moved downwardly to drive arm 17@ in a counterclockwise direction to move crank 17S in a counterclockwise direction to pivot wall gli and the movable shelf portion 3@ to the broken line position shown in FTGURE 4. When this occurs, the nickel which had come to rest on the movable shelf portion 3@ and coins caught in the bucket 82 fall downwardly and out through opening I8@ to guide 184 which directs the coins to a coin return slot (not shown) at which they are accessible to the depositor. It is to be noted that since wall is pivoted at its bottom while wall 96 is pivoted at the top, there is little danger that a coin will be caught between the walls.

It will be seen that we havevaccomplished the objects of rour invention. We have provided a coin shelf and escrow bucket which overcomes the deliciencies of coin mechanism of the prior art. Since our mechanism holds only a single vcoin of the denomination given in change in escrow for movement into the change coin tube when the coins are accepted, there is no danger that two thin coins of the kind given in change will cause the machine to jam. The construction of our escrow bucket is such that there is little chance of a coin being trapped between the bucket walls. We have provided a very simple mechanism for returning both the change coin held in escrow and the coins in the escrow bucket to the customer in the event that the customer wishes the return of deposited coins.

It will be understood that certain features and subcombinations are of utility and may be employed without reference to other features and subcombinations. This is contemplated by and is within the scope of our claims. It is further' obvious that various changes may be made in details within the scope oi our claims without departing from the spirit of our invention.
